Can't ping IPv6 address [IPv6 module not loaded? Routing table issue?]

Dear Arch community,

although I know that -- according to the Wiki -- IPv6 should be set up by default on Arch I am struggling with getting IPv6 connections on my install with kernel

uname -r
6.4.6-hardened1-1-hardened

Whenever I ping an IPv6 address, e.g. an openNIC-DNS server, via both my ethernet and wifi interface I get the error 

ping -6 2a03:4000:28:365::1
ping: connect: Network is unreachable

but the interface has got a (local?) IPv6 address assigned (wifi connection established):

ip -6 a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen 1000
    inet6 ::1/128 scope host noprefixroute 
       valid_lft forever preferred_lft forever
3: wlp61s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
    inet6 fd00::c314:XXXX:XXXX:XXXX/64 scope global dynamic mngtmpaddr noprefixroute 
       valid_lft 6647sec preferred_lft 3047sec
    inet6 fe80::60e2:XXX:XXX:XXXX/64 scope link 
       valid_lft forever preferred_lft forever

Everything works fine for another hardened-kernel Arch and two further Debian-based systems in the same network so it should not be a router or ISP related issue but with the system under consideration the IPv6 connection fails in every network which I tested it in.

I've run through the procedure *here* to test if the IPv6 module is disabled which seems not to be the case:

cat /proc/net/if_inet6
fe8000000000000060e20e6ae8ab75c6 03 40 20 80  wlp61s0
00000000000000000000000000000001 01 80 10 80       lo
fd00000000000000c3147f7afac159ee 03 40 00 00  wlp61s0
cat /sys/module/ipv6/parameters/disable
0
sudo sysctl -a | grep disable_ipv6
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.enp0s31f6.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0
net.ipv6.conf.wlp61s0.disable_ipv6 = 0

After loading the module, however, modinfo shows information but lsmod does not seem to find the IPv6 module loaded:

sudo modprobe ipv6
modinfo ipv6
name:           ipv6
filename:       (builtin)
alias:          net-pf-10
license:        GPL
file:           net/ipv6/ipv6
description:    IPv6 protocol stack for Linux

parm:           autoconf:Enable IPv6 address autoconfiguration on all interfaces (int)
lsmod | grep ipv6
[empty outout]

The module appears to be installed though:

ls /lib/modules/6.4.6-hardened1-1-hardened/kernel/net/ipv6
ah6.ko.zst           ila                    ip6_vti.ko.zst  sit.ko.zst
esp6.ko.zst          ip6_gre.ko.zst         ipcomp6.ko.zst  tunnel6.ko.zst
esp6_offload.ko.zst  ip6_tunnel.ko.zst      mip6.ko.zst     xfrm6_tunnel.ko.zst
fou6.ko.zst          ip6_udp_tunnel.ko.zst  netfilter

Just now after gathering all this information I found an odd situation in my routing table:

route -6
Kernel IPv6 routing table
Destination                    Next Hop                   Flag Met Ref  Use If
fd00::/64                      [::]                       U    3003 1      0 wlp61s0
fe80::/64                      [::]                       U    256 2      0 wlp61s0
[::]/0                            [::]                       !n   -1  1      0 lo
localhost/128                  [::]                       Un   0   3      0 lo
mydevice/128                 [::]                       Un   0   2      0 wlp61s0
mydevice/128                 [::]                       Un   0   3      0 wlp61s0
ff00::/8                       [::]                       U    256 9      0 wlp61s0
[::]/0                         [::]                       !n   -1  1      0 lo

Doesn't that mean that all general traffic ([::]/0) is going back through the loopback interface (lo) ?? What does the "!n" flag mean? Why are there two "mydevice/128" entries? Unfortunately I don't know enough about routing to fully understand this output... If someone knows about good literature (online or offline) I'd be glad for every hint!

Thank you in advance and all the best,

Re: Can't ping IPv6 address [IPv6 module not loaded? Routing table issue?]

Because your network stack has/acquires an ULA address (fd00::/16) IPv6 is working.

Your problem is the connectivity beyond link-local and ULA addresses.
ULA addresses will not be used for access beyond your router.

How do you manage your network connections?

Re: Can't ping IPv6 address [IPv6 module not loaded? Routing table issue?]

Ok, that's good to know at least! I guess I need to read a bit about IPv6 in general.

All I do -- in case of wifi -- is setting up the interface, starting the dhcpc client and starting wpa_supplicant with the respective driver and config file containing the network's SSID/PSK which I include manually for every network:

ifconfig wlp32s0 up
dhcpcd 
wpa_supplicant -D wext -i wlp32s0 -c /etc/wpa_supplicant/wpa.conf

Wrote a small bash script for that, no further "managing" involved.

What about that routing table? I never saw that "!n" flag before and it's not even contained in the man file of route. But there it is stated that "!" means  "reject route"...

Re: Can't ping IPv6 address [IPv6 module not loaded? Routing table issue?]

Run wpa_supplicant first, add "-d" to the parameters and post the output you get.
Then, when it looks like you've a carrier, run "dhcpcd -dB" (it'll not fork), wait a minute (get a cup of coffee) and post the output of that as well.

Edit: sanity check
Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Hey Seth, thanks for your help!

That's a damn lot of output although I shortened it a bit:
